They 100% work -- if they didn't, QGIS wouldn't be good for anything
except wasting some space on your computer ;)

I suspect this is where the issue sits -- try checking

assert VectorLayer.isValid()

here. My suspicion is that your relative path 'Vector_layer.shp' is
not working, and will need to be an absolute path.
